What is the biggest crater on Mars?

The largest impact basin on Mars is the Hellas Basin (also known as the Hellas Planitia), located in the southern hemisphere of the planet. This ancient impact crater has a diameter of 2,299.16 km (1,428 miles) and is 7.152 km (4.44 miles) deep (measured from Martian zero elevation).

What is the biggest asteroid that hit Earth?

The largest meteor to have entered Earth’s atmosphere is called the Chelyabinsk meteor, and it exploded over the Russian city of Chelyabinsk that was home to more than one million people in 2013. The Chelyabinsk asteroid was just 50 feet in diameter and exploded with a force the same as 440,000 tons of TNT exploding.

Meteors, comets and asteroids have slammed into the earth with a force many times greater than the most powerful nuclear bombs. Sometimes, mass extinction followed. There are roughly 180 known impact craters worldwide and fully a third of them—including some of the biggest—are located in North America.

How are craters formed on Earth?

Craters are formed by the outward explosion of rocks and other materials from a volcano. Calderas are formed by the inward collapse of a volcano’s magma chamber. Craters are usually much smaller features than calderas, and calderas are sometimes considered giant craters.
